Copernicus
100
What is Newton's 1st Law?
What is the law of inertia, objects stay in rest/motion unless acted upon by a nonzero net force.
100

What is Newtons.
200
What is the name given to the force that acts between materials that touch as they move pas each other?
Friction
200
What is the motion that was originally thought to impact planets and stars?
Natural, not thought to be caused by forces.
200
What happens if friction were absent to a moving object?
No force would be needed for the object to remain in motion, it would travel in a straight line

What happens when an object has a greater mass, in regards to it's inertia?
